1. Push the lens.

Pushing the lens means that the lens points to the subject, and the photographer keeps walking into the subject and shooting.

This technique can play a prominent role in introducing people or things in the film, and make the audience's attention shift from the whole to the part. The less things the picture contains, the more focused the audience will be.

2. Pull the lens.

Pulling the lens is just the opposite of pushing the lens, which means that the camera keeps moving away from the object.

Pulling a shot can not only show the position of the main character or scene in the environment, but also reflect the relationship between the part and the whole, and can also connect the transition between shots, such as the transition between close-up shots and scene shots. It will be natural to pull a lens to connect them.
